Development of Bioproductive Soil Mixtures Using Subway Construction Waste for The Purpose of Improving the Territory of The City

Abstract

The article presents the results of research on the bioproductivity of ecologically clean waste generated during excavation work on subway construction sites and other underground construction. It is proposed to use waste as one of the components of soil mixture preparation. In the course of the work, soil mixtures varied in relation to the waste/peat soil. A number of laboratory experiments on the germination of a lawn grass mixture, widely used in the improvement of cities, was set up. Based on the results of the work, recommendations were proposed for compiling a methodology for studying artificial soil mixture

Capacity of Air-and-Screen Grain Cleaner as Component of Production Line of Sunflower Meal

“…Application of the proposed integrated systems in combination with the main production technology of combined feeds makes it possible to improve technical and economical performances, and to develop real possibilities to save resources and to improve quality of final products [30][31][32][33][34]. The technology can be improved by combination of two procedures (postharvest processing of a heap of sunflower seeds using air-and-screen grain cleaner and its extrusion to produce protein feed).…”
